" We have never understood why men mount the heads of animals and hang them up to look down on their conquerors. Possibly it feels good to these men to be superior to animals, but it does seem that if they were sure of it they would not have to prove it. Often a man who is afraid must constantly demonstrate his courage and, in the case of the hunter, must keep a tangible record of his courage. For ourselves, we have had mounted in a small hardwood plaque one perfect borrego [bighorn sheep] dropping. And where another man can say, "There was an animal, but because I am greater than he, he is dead and I am alive, and there is his head to prove it," we can say, "There was an animal, and for all we know there still is and here is proof of it. He was very healthy when we last heard of him. "
